IMIROVEMENT IN HARVESTER-CUTTERS.

Specification forming part of Letters Patent No. 139,695, dated J une 10,1873; appliiation filed July 15, 1872.

To all whom it may concern:

Be it known that we, SAMUEL H. WEL- LLNGS and SIMON Scores, of Bridgcville, in the county of Gratiot and State of Michigan, have invented a new and usef 1 Improvement in an Endless-Chain Harvester-Sickle; and we do declare that the followin g is a true and accurate description thereof, reference being had to the accompanying drawings and to the letters of reference marked thereon and being apart of this specification, in which- Figure 1 is a plan of a part of our endlesschain harvester-sickle, and Fig. 2 is a perspective view of a link and sickle.

Like letters refer to like parts in each figure.

The nature of this invention relates to that class of endless chain harvestersickles in which each link is provided with a sickleknife instead of every second link. The invention consists in the peculiar construction of thecombined link and sickle section, as more fully hereinafter set forth.

In the drawing, A represents a steel sickle knife or section, which may have cast or forged on it two link-bars. A A, extending beyond the heel from the base, and not extending to the other extremity of the base. If preferred, the link-bars may be made separately and riveted to the base of the sickle.

As the chain moves and cuts continuously in one direction, the sickles are beveled and ground on one edge only.

In making up the chain the base-corner of a sickle is inserted between the projecting ends of the bars A of the next sickle, and

pivoted therein bya riveted pin, a, and so on, the heel of one sickle fitting snugly against the back edge of the next, when the chain is v extended on a right line, so that grass or grain cannot clog between them, but must be cut by the sickle-edge.

By removing the chain from the machine the sickles may be ground on a common stone without removing them from the chain. As each sickle is presented to the stone, the adjacent sections are swung back out of the way.

Heretoforc endless chain harvester sickles were made and fitted with sickles at every
